4 Claims.

The present invention. relatesito improvements indoorstops.: andrelates more particularly to convertible. doorst'opsoia ytype which maybe convertedv for use either Verticallygor horizontally.

Themain object -offthefpresent invention is to rovide a. superior.- doorstop having elements so constructed and,ia11ranged-.as.to -be'readily convertedxforpuse-eithenin a..verticalI position (as Whenmounted upon a iioor` orthelike) or for use in af-horizontal.v position (as When mounted on a baseboardor lthe like) Another object of the present invention is to provide asuperior convertible doorstopcombim ing convenience andreliability in use vwith lowA cost` for manufacture.

Withthey above and-,other objects in view, as will appear. tothosev. skilled in the art from the present` disclosure, this invention includes all featuresinthe said disclosure which are novel overthe prior art and which are not claimed in any separate application.

Thel structure-of Figs. 1 to 7 inclusive The convertible doorstop illustrated in Figs, 1 to '-7 inclusive of the accompanying drawings, includes a fbody-member I0, a head-member iI and a clamping-screw I2.`

Thebody-'member` I0:.inc1udes a relativelybroadii base-portion I3"f'r.om which extends a tapering'ishankil. surmounted by an; integral.

substantially-hemispherical portion i5 having an oblique clamping-face I6 which, in the Vinstance shown, is disposed obliquely at an angle of 45 with respect to the base-portion i3.

The head-member Ii includes a substantiallynomi-spherical portion I having a clamping face the hemispherica-leportion i8 adapted to engage with the clamping-face I5 of the body-member i. The said head-member also includes an integral neck i9 projecting o'bliquely with respect to the clamping-face I8, In the instance shown,v the clamping-face ifis disposed at an angle of`45 with respect to the longitudinal axis of the neck lil, While the latter has mounted on its outer end a buffer 2i! which `may be formed 'oiany suitable resilient material such, for'instance, as rubber.

Formed in the hernispherical-portion I'! of the head-member il and extending centrally in a direction perpendicular with respect to the clamping-face i8 is a threaded socket 2i' extending in axial alignment With respect to la clearance-passage 22ior1ned inthe hemisphericalportion I5 of the bodyemember IQ. The clean ance-passage intersects the clamping-face i@ of I5 just referred to, and the opposite end of the said clearance-pas sage is enlarged to provide a recess 23 for the accommodation' oi the .head `of theclampingscrew i2. The clamping-screw freely ts the .clearance-passage 22 in the hemispherical-portion I5 of the body-member li),V but has threaded engagement with thethreaded socket 2| inthe hemispherical-portion i? oi the head-member lI, and serves to rmly clamp the clamping-face ;I 8 oi the said head-member I I against the clamp ing-face d6 of the body member Iii.

Preferably and as shown in Fig. 4, the bodymember Ill is formed with a threaded socket 2t extending coaxially Within the shank ifi and lintersecting the outer face of the base-portion i3. A mounting-screw, bolt or other suitable fastening-device may be threaded into the socket 2e to mount the convertible doorstop in any desired position,

In Figs. 1 to 4 inclusive,l the body-member it is shown in the position which it might assume if mounted upon a oor surface, while the headmember l i is turned so that its neck I9 and hence its buffer Eil project perpendicularly with respect to the body-member il] and hence horizontaily in a position to act as a stop for a door or the like.

By loosening the clamping-screw i2,`the headmember II may be reoriented relative to the. body-memberi and brought, for instance, into the position indicated in Fig. '7, following which the clamping-screw would be again tightened. As illustrated in Fig. 7, the convertible doorstop is suitable for use in a horizontal position such, for instance, as by having its base I3 secured against the face of a baseboard, under which conditions the buffer 20 is in position to act as a stop for a door or the like.

The structure of Figs. 8 and 9 The convertible doorstop illustrated in Figs. 8 and 9, includes a body-member 25, a head-member 25 and a clamping-screw 2l.

rI'he bodymember 25 includes a base-portion 23, a shank 29, and a heinispherical-portion 3! at the end of the shank 29 opposite from which the base-portion 28 is located. The hernispherical-portion 30 just referred to, is formed with an obliquely-disposed clamping-face 3i against which is located a spacing-washer 32. Arranged centrally and perpendicularly with respect to the clamping-face 3l, is a clearance-passage 33 which extends through the hemispherical-portion 33 of the body-member 25. The said clearance-passage 33 is enlarged at its end opposite the clamping-face 3i to provide a recess 3d for the accommodation of the head of the clampingscrew 2.

The head-member 25 also includes a substantially-hemispherical portion 35 having an obliquely-disposed clamping-face 36 adapted to be clamped against the adjacent face of the spacing-washer 32. The head-member is also formed with a threaded socket 31 threadedly receiving the end-portion of the clamping-screw 2.

Like the head-member Il before referred to, the head-member 25 is provided with a neck 38 having its axis extending at about 45 with respect to the plane of the clamping-face 36 and mounting a buffer 39 formed of rubber or other suitable resilient material.

The diameter of the spacing-washer 32 preferably substantially-corresponds to the respective diameters of the clamping-faces 3! and 33 so as to complement the contours of the portions 33 and 35. The spacing-washer 32 is formed with an eccentrically-located eye-po-rtion 4| in which is pivoted the inner end oi a hook 52, which latter may be utilized to hold a door or the like in an open position. The spacingn washer 32 and its eye-portion 4| may be turned in any desired position to permit the hook i2 to accommodate itself to the requirements of various situations. If no hook 42 or the like is desired, the spacing-washer 32 may be replaced by a plain circular washer.

General From the foregoing, it will be seen that a head-member may be turned with respect to a body-member to enable the doorstop to be con verted for uses in various positio-ns.

While, as above described, a given head-portion has been shown either as extending at a right angle with respect to a given body-member or as extending in parallelism therewith, many intermediate positions of a given head-member with respect to a given body-member may be utilized to accommodate the convertible doorstep to meet requirements of many diierent types of installations.

The invention may be carried out in other specie ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore. to be considered in all respects as illustrative and not restrictive, and all changes coming Within the meaning and equivalency range of the appended claims are intended to be embraced therein.
